Self-repair is extremely important for living things. Get a cut on your finger and your skin can make new cells to heal the wound; lose your tail—if you are a particular kind of lizard—and tissue regeneration may produce ...

What if repairing large segments of damaged muscle tissue was as simple as mobilizing the body's stem cells to the site of the injury? New research in mice and rats, conducted at Wake Forest Baptist Medical Center's Institute ...

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some ...

Just because a lizard can grow back its tail, doesn't mean it will be exactly the same. A multidisciplinary team of scientists from Arizona State University and the University of Arizona examined the anatomical and microscopic ...

Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell's territory, eventually ...

What does it take to regenerate a limb? Biologists have long thought that organ regeneration in animals like zebrafish and salamanders involved stem cells that can generate any tissue in the body. But new research suggests ...

Almost a century after it was discovered in fruit flies with notches in their wings, the Notch signalling pathway may come to play an important role in the recovery from heart attacks. In a study published today in Circulation ...

Bioengineers from University of California, San Diego are developing new regenerative therapies for heart disease. The work could influence the way in which regenerative therapies for cardiovascular and other diseases are ...
